SkyFootprint

SkyFootprint is a mobile + web app that shows real-time satellite ground tracks and, more importantly, the approximate “who can see what” footprint for common Earth-observation satellites. Users can drop a pin or draw a polygon (farm, facility, port, neighborhood) and get upcoming overpass times, look angles, and a plain-language visibility summary (e.g., “likely imaging window” vs “low probability”). It’s not a spy tool: it uses public TLEs, published sensor constraints, and conservative assumptions to estimate visibility and revisit frequency. The app also provides historical overpass logs so users can correlate events (construction, shipments, weather) with when imagery was likely captured. This is a practical geography-first interface for satellite location intelligence, aimed at compliance, security planning, and operations—not hobbyist skywatching.
